Utilities in
many areas of the country offer two electric rates for residential
or commercial customers. One rate has the regular daytime
electrical rate, the other is the “off-peak” rate. The “off-peak”
rate provides customers with “lower-priced” electricity during the
nighttime and weekend periods. These time switches allow the
customer to shift electricity use into these “off-peak” time
periods in an attempt to save utility costs.
